FIELD OF THE INVENTION

The present invention is directed toward cabinets for housing electronicequipment. More particularly, the present invention relates to a cabinetfor housing electronic equipment and a connection panel forcross-connecting the electronic equipment with various provider and/orsubscriber lines, wherein the cabinet includes a fuel cell power backupsystem, and more particularly, to a fuel cell cabinet having a wastewater management system.

BACKGROUND OF THE INVENTION

Outdoor cabinets that house electronic equipment and connection panelsare generally known in the art. The connection panel (sometimes referredto as a feeder-distribution interface), within the cabinet, is used toconnect subscriber lines to provider lines directly, or in parallel orserial, with terminals of certain electronic equipment also within thecabinet, such as surge protectors, switches, servers, etc.

In some conventional cabinets, the electronic equipment includes a fuelcell power backup system. A fuel cell, such as a hydrogen fuel cell,combines hydrogen fuel and oxygen from the air to generate electricity.As a result of the combination of the hydrogen fuel and the oxygen,water flows from the fuel cell. Therefore, the water flow needs to bemanaged, for example, to prevent damage to the fuel cell cabinet systemand/or electronic equipment.

Some conventional fuel cell cabinets commonly drain the water on thesurface of ground (i.e., above grade), which may cause water damage tothe cabinet, such as the base of the fuel cell cabinet, or thesurroundings of the fuel cell cabinet, such as the surface on which thecabinet is mounted. Additionally, the draining water can sit abovegrade, which may be visibly unpleasant to a user. The water sittingabove grade may result in wet or muddy ground conditions, or which mayfreeze on the ground in colder environments.

Some other conventional fuel cell cabinets commonly capture and storethe water, for example in a container or bucket, for subsequent removalby a services technician or company. These conventional approaches mayresult in increased costs associated with maintaining the system, suchas the cost of removal of the captured water. Additionally, theseconventional approaches may require timely service to preventoverflowing of the container or bucket used to capture the water, whichmay add to the complexity of operating and managing the system. Further,the container or bucket takes up space within the fuel cell cabinet orresults in an increased size requirement for the fuel cell cabinet.

SUMMARY OF THE INVENTION

These problems and others are addressed by the present invention, afirst aspect of which comprises a fuel cell cabinet including a wastewater management system for a fuel cell, wherein the waste watermanagement system manages a flow of water from the fuel cell to one of acontainer and an exterior of the fuel cell cabinet.
